cUTTEE-MoUNTine -Eon rArEE-EOL'L HOLDERS.

Be it known that I, Firearms` M. House,

aV citizen of the United States, residing at Richmond, in the county of `Henrico and V{t-ate of Virginia, have invented certain new and useful 'lmprovements in Gutter- Mountings for `Paperloll vl-lolders, of

, cally flat againstthe periphery of the paper l()` the cutting blade and upon the cutting blade which theV following is specification, ref :erencebeing had to thev accompanying drawings. f

.This inventionV relates to holders. for holding rollsof papers,`and particularlyrv to ,certain improvements in fthe paper rolll holder illustrated and claimed in theV patent granted to me on` August 26,. 1919, No. 1,314,267.

y In the paper roll holder illustrated in this patent, there is shown al cutting blade which extends parallelto the paper roll and which is movable away from the of thepaperV roll spindle but which. 'is resiliently urged toward the paper roll spindle so as to `bear 'at all 'times against the 'faceof'the' paper carried lby said roll. The cutting blade Iin this patent is rigidly mounted upon-supporting arms and as a consequence, the blade takes different angular positions relative to the paper as thediameter of thepaper roll j decreases, in other words when the paperr roll is of full size the blade extends practiroll, then asithe paper is removed from the roll and the blade moves. inward, it gradually increases its angle to the paper. I have foundin lactual practice that blades dolnot cut asv well' when they are disposed flat against the-roll of paper as they'do when the blade is r disposed atan angle thereto,

andthe general Objectof this present invention is to improve uponthe mounting for itself so that the cutting blade will at all timeshave the same angularposition relative to the periphery ofthe paper roll without regard to whether the rollV ofpaper is relatively large or relatively 'small in diame-V ter. y

VA further object is toprivotally mount the'blade upon the supporting arms" and provide the blade with a portion which-'bears against the paper and acts to hold they blade in' correct relation to the paper "Without regard to the movement of thesupporting arms. v

Other Objects will appear inthe course of the follow-ing description. Y

- My vinvention is illustrated in the accompanying drawings, wherein Figure lyis a side` elevation Vof a paper vroll holderwith my improved blade mounting thereon; i, 1 Fig. v2 is section taken just abovefthe arm V21 looking down on the roll Fig. 3 is a fragmentary perspective view ofthe connection between thelv arms y1.7 and 21; Y a

Fig. 5 is a'sectional perspective view `of the rivet; y Y Y Fig. 6 isa fragmentary top plan View" Ashowing the means for holding the upper end ofthe roll in place on the spindle.

As my paper roll lholder is fully illustrated in the patent above referred to, it is only `necessary to sayV :that the paper roll holder comprises a base 10 which 'is preferably made ofcast metal and formed with The marginof the base is downwardly turned or flanged, as .at 13, vand the `base is provided with apertures `for holding screws.

Extending upward fromk .thev base is la spindle 14C which is detaehably connected to f the base. `The roll of paper ,A restsupon' a plate Vl5 which supportsvthe lower centering ycollar for the paper (not shown). v

For the purpose of supporting the Vcutting blade by which the paper is 'y out, I

mount upon the boss 16 on the lbase 10l the lever 17 which is pivoted, at 18, andwhich is drawn in one dlrectlonby a contractile spring'lQ. This lever is formed at its outer end with avertieal sOcketZO. LThe arm 2l has its outer extremity fangularly bent, as

at 22, andinserted in this socket, and this arm 22 is connected tothe cutting blade 23;

Vinanianner whichwill Ybelater stated. y At its upper` end, the blade23 Ais likewise eonnected ina manner which will lbeflater stated to Van arm 24: which is pivoted upon Van-arrn'26.-`v The upper end of' thespi'ndle l av triangular head 37 which bearsV against and forms" a tulcrum .for Athe cutter' 23.4

arm 26 to the spindle.

v as to urge this arm inward.

14; is reduced in thickness, as at 27, and the extremity oi the arm 26 1s formed with a notch snugly fittingthis reduced portion.

The reduced portion 27 or" the spindle isV m i datent above referred to exce at that in the patent above referred-to, the angular end 22 ot the arm 2l is not disposed in the socket 2O in the lever 17. lt will be seen that the spring 19 and 30 act to urge the arms 24.- Vand 2l toward the paper Vroll and resiliently -torce the blade 23 against the paper roll. Y

.The blade 23 is approximately U-shaped. The blade is made ofsheet metal and is formed toprovide the inner side wall 3:1 and the outer side wall 32. Thev edge o1 the, outer side wall is deflected outward, as at 33, this Vwall 33 forming the blade proper against which `the paper is cut. The wall is outwardly turned along its margin, as at 34, so as to bear yieldingly against the periphery or Vthe paper roll A. The Vside wall 3l at its upper and. lower ends is formed Awith relatively large periorations 35 through which the arms 2l and 2J: extend. Thesearms 21 and 2li are relatively small in comparison with the slots Each oi" these arms at its endl within the `lei-shaped cutter 23 is provided withV a rivet, the shanlr36 ot which extends through a pert'oration in theouterface "ofthe member 23,l

and is provided with the usual head, .the mner end of this shank being provided with This rivet, it will Vbe understood, extends all times from the arms 2.1 and24f at the same angle, but the .cutter Ymay roch upon Under these circumstances, it will be seen that the cutter 23 bears at all times against the periphery oi the paper roll at two points, namely atthe edge of the deiieotcdfcutting margin 33 and the edge ofthe rounded pori tion Thusl no matter whether the )a )er roll be large orsmall, the cutting edge 33 willy always be disposed at exactly the `saine curvature ot. the periphery of the roll, due f vangle to the paper and the difference in to the differences in diameter of the roll, will pivots. The part 34 constitutes means, it

simply act to shift the cutter 23 uponits ward the spindle ot the paper roll.

When the paper roll has been exhausted ,for the cutter which are resilientlv uro'ed to-` v in place on the holder, the latch 29 is re- 'an'd' it isdesired to place-a new` paper roll leased'from its engagement with the upper and then the arm 26 engaged with the upper end of the spindle la place by the latch 29.,
